Angular Angular speed Revolutions Speed

AI Thread Summary

The discussion revolves around a problem related to angular speed and revolutions, specifically focusing on question 22, which poses a challenge for the participants. The initial approach of setting dtheta/dt to 0 is deemed incorrect, indicating a misunderstanding of the problem's requirements. Participants suggest setting up a definite integral with appropriate limits to solve for the time when the wheel comes to rest. This highlights the importance of correctly interpreting the problem and using the right mathematical tools. The conversation emphasizes the need for a different approach to reach a solution.

I've attached the problem as an image. I solved 20 and 21 very easily. For 22, my obvious instinct was to set dtheta/dt to 0, but that's an unsolvable equation. I'm obviously missing something key in solving 22. What is it?

obviously, your obvious instinct is not pointing you to the right direction...

Try to set up a definite integral with appropiate limit... (what is time t equal to when the wheel coming to rest?)

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
